STEM WINDING AND SETTING WATCH.

EPBGIEIGA TION forming part of Letters Patent No. 350,407, dated October5, 1886.

Application filed May 8, 1886. Serial No. 201,565. (No model.)

To aZZ whom it may concern:

Be it known that I, ABRAHAM M. YEAKEL, a citizen of the United States,and a resident of Perkasie, in the county of Bucks and State ofPennsylvania, have invented certain new and useful Improvements inVatches; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeinghad to the accompanying drawings, which form a part of thisspecification, and in which Figure 1 is a face View of a watch with theface removed, showing my improved stem setting and winding mechanism.Fig. 2 is a similar view showing the device applied to a hunting-casewatch. Fig. 3 is a sectional view of the pendant. Fig. 4 is aperspective view of the separate parts of the pendant. Fig. 5 is a viewof the winding and setting mechanism seen from the rear side or in adirection opposite to the direction seen in Fig. l, and Fig. 6 is aperspective detail View of the easespring for a hunting-case watch.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of stem winding and settingwatches in which the cog-wheels or pinions which engage the cog-wheelsupon the post of the mainspring and the cogwheels of the hands arejournaled at the ends of a yoke having a common cogwheel engaging thecogwheels at the ends and engaging the setting and winding pinion, andin which this yoke may be tilted, so as to engage either the winding orsetting mechanism; and it consists in the improved construction andcombination of parts of the same, as hereinafter more fully describedand claimed.

In the accompanying drawings, the letter A indicates the front plate ofthe casing of the works, and B is a cogwheel secured upon the post ofthe mainspring, which is journaled in the said plate to one side.

0 is the cog-wheel which meshes with the pinion upon the post of theminute-hand of the watch, and which is provided with the pinion D, whichmeshes with the cog-wheelE upon the sleeve of the hour-hand, and thiscog-wheel is placed at the opposite side of the stem of the minute-handto the cog-wheel upon the stem or post of the mainspring.

A yoke, F, has a central circular aperture, G, with which it is pivotedupon a circular disk, H, secured to the front plate of the case, andthis disk is considerably thicker than the yoke, having a cogged ring,I, turning upon it, the said ring having outwardly-proj ecting cogs andinwardly-facing beveled cogs J, as plainly seen in Fig. 5. This yoke isformed with inwardly-projecting pins K and L at its ends, and cog-wheelsM and N are journaled upon these pins, bearing against the face of thefront plate with their inner faces, and meshing with the central coggedring. The cog-wheel M meshes normally with the winding cog-wheel, whilethe other cog-wheel, N, may mesh with the cog-wheel of the settingmechanism when the yoke is tilted, so as to disengage the cogwheel fromthe windingwheel and force it toward the setting cog-wheel.

A spring, 0, is secured at one end near the edge of the front plate ofthe casing, and the inner free end of this spring bears against a pin,P, projecting inward from the yoke above the cog-wheel which meshes withthe setting mechanism, forcing that end upward and forcing the endhaving the winding-wheel downward, so as to mesh with the wheel upon thepost of the spring, and this end is prevented from being tilted too fardown by a projecting lug, Q, upon the end of the yoke bearing against ascrew or stud, R, upon the front plate. The eogged ring meshes with abeveled pinion, S, secured upon the lower end of a stem, T, or shaft,the upper end of which is formed into either a polygonal tap or apolygonal socket.

A pin, U, slides through a perforation in the upper portion of the sideof the casing and in an eye, V, within the casing, and the lower end,XV, of this pin is bent forward and slides in a slot, X, in the frontplate of the casing bearing against the upper edge of the end of theyoke having the setting-wheel, while the upper end of the pin projectsthrough said perforation in the side of the casing.

The case-center Y of the watch has the inner or lower end, Z,of thependant A secured into it, and this pendant is formed with sockets orrecesses in its side to receive the ends of the bow-ring B,while itsupper end, 0, is re duced and provided with a removable flange or ring,D. A ring, E, fits with its central perforation upon the reduced end ofthe pendant, and has its upper reduced and screw- 5 threaded end Fbearing against the remov- D, which is preferably clinched or riveted tothe inner side of the top of the cap projecting down through an axialperforation, L, in the pendant. The lower end of this stem or keypipefits in or upon the socket or tap projecting up through the side of thecasing for the works, so that the works may be wound or set by theturning of the stem or key-pipe and its cap and ring, and the stem orkey-pipe is provided with a flange, M, which bears against the upperside of a perforation, N, in the easespring 0, which is secured insideof the casecenter, and has its outer end bearing against the pinprojecting out through the side of the inner casing. It will thus beseen that when the cap and ring are revolved the mainspring maybewound,the winding-wheel being placed with its teeth at such an angle tothe teeth of the wheel 13 upon the mainspring-arbor that when thewinding-wheel is revolved backward its teeth will slip over the teeth ofthe other wheel, while its teeth will engage the teeth of the otherwheel when wound forward, the teeth of the winding-wheel sliding inbetween the teeth or cogs of the wheel upon the-mainspring-arbor whenrevolved forward, while when revolved backward the sides of the teethwill strike the ends of the teeth or cogs of the wheel upon themainspring-arbor obliquely, so that they will slide over them, thespring at the other end of the yoke allowing the cogs of the wheels toslide over each other, while they will be forced back, meshing with eachother by the. spring at the same time.

, \Vhen the watch is to be set, the cap and ring are forced inwardagainst thecoiled spring, and the flange or collar of the stem orkey-pipe will bear against the case spring, which again in turn willbear against the end of the pin,which will tilt the yoke with its innerbent end, causing the settingswheel to mesh with the setting mechanism,so that by turning the cap and the stem or key-pipe the cogged rim andthe setting-wheel may be revolved. The spring bearing against the studat the end of the yoke having the setting-wheel will raise that end ofthe yoke and will raise the pin, so

A colled spung, H, 1s se-c that it will again project when thepressure'is removed from the cap.

In a hunting-case watch the case-spring is preferably constructed asshown in Fig. 6 and in Fig. 2, the free end of the spring being splitlongitudinally, and the upper portion of the split end is provided withan outwardly-pro jecting latch-lip, P, which engages the lip of thecover,'while the lower portion, Q of the split end is thicker or stifferthan the upper end and carried beyond the end of the same.

The flange or collar upon the stem or keypipe only bears against theedge of the perforation of the lower and longer portion of the spring,and when the said stem or key-pipe is pushed in the lower stiffer endwill draw the upper portion will catch with its latch-lip againstaportion of the inside case or other portion of the casing, stoppingit,while the lower portion will be pushed sufficiently far in to allowthe hands to be set.

The coiled spring and the case-spring bearing up against the ring, theupper end of this ring will be forced perfectly tight against the flangeor collar at the upper reduced end of the pendant, forming a dust-tightjoint, and the lip of the swivelring sliding tightly against the outerside of the pendant will assist in making the pendantperfectly dust andwater tight, excluding all dust anddampness, so that if the casing ofthe watch is perfectly tight no dustorr dampness will be admittedthrough the pendant, and the watch will be perfectly protected.

The pendant may be used with open-faced as well as with hunting-casewatches, and may be used in stem-winding watches as well asinkey-winding watches, as thependant is useful as well for simply openingthe caseof a watch as for winding it, or for opening the case and forwinding it, forming in all cases and forall purposes a tight joint forthe stem or key-pipe the ring firmly and thereupon turn the cap'backward, when the cap will be unscrewed and the stem or key pipe may beremoved, when the works may be taken out in the usual "manner, and whenthe works are to be insertedinto the case the stem or key-pipe may befitted into its proper socket or upon its proper tap, whereupon byrevolving the ring and holding the cap firmly the ring may bescrewedinto the cap, drawing the cap downward and securing the same. a

The casespring will assist the coiled sprin in holding the ring upagainst the flange or collar upon the reduced portion of the pendant,and if the coiled spring should by accident be disabled the ease-springwill be able to perform its duties, together with its own, so that thependant will remain operative.

By this construction of the winding and setting mechanism the hands maybe set by simply pushing the cap and ring inward, avoiding the necessityof pushing a setting-lever in or drawing it out, as inusually-constructed stem winding or setting watches, avoiding troubleand preventing the possibility of keepingthesettinglever in positionafter the hands have been set, in which position the works will bestopped.

Having thus described myinvention, Iclaim and desire to secure byLetters Patent of the United States- 1.
